Growing & Care of Malus Rudolph

They can be round or elongated in shape and against the foliage, making a stunning garden feature. They are hardy too, resisting some of the common apple tree pests. Once you have planted your Rudolph crab apple tree, you can expect it to bear fruit within 2 – 5 years. Its eventual height will be up to 7 metres and the crown becomes rounded with maturity.

Common Pests & Diseases

Although often resistant to apple scab which is a plus, Rudolph crab apple trees can fall victim to some problems.

  • Red Spider Mite:  These mites feed off of the sap found on crab apple trees which can cause leaves to drop early. They can be troublesome between March and October when conditions are dry and warmer. Regular watering and removing any signs of an infestation is usually enough to deal with this issue.
  • Apple Canker: A fungal disease, apple canker can cause the bark to die or appear sunken. The infection can take hold if there is a wound on the tree although it often begins on the bud. Any affected wood will need removing to prevent the disease from spreading further.
  • Honey Fungus:  Armillaria, a fungus that attacks plants and wood, is often given the name honey fungus. It gets its name from the appearance of honey-coloured mushrooms that often show up on the surface. Any infected wood should be removed and burnt to stop the spread.

History of Malus Rudolph

A close relation of Malus Niedzwetzkyana, Malus Rudolph was developed in Canada in 1954. It was raised by F.L. Skinner and named after the infamous reindeer Rudolph due to its rosy red flowers.
